Items with more than one hazard #464

Closed idolum closed 11 months ago

idolum commented 11 months ago

Some goods may have more than one hazard:

Example 1: A hazardous material meets the defining criteria of Division 2.1 Flammable gas and Class 8 Corrosive material. Answer 1: Division 2.1 Flammable Gas is higher on the list (3) than Class 8 Corrosive material (8). Therefore Division 2.1 Flammable gas is the primary hazard class and Class 8 Corrosive material is the subsidiary hazard class.

Example taken from https://danielstraining.com/classification-of-a-material-having-more-than-one-hazard-49-cfr-173-2a/

So, in this case, two a primary and a secondary hazard has to be described in the catalouge. Right now, this is not possible, as the cardinality of epo-cat:hasHazardousClass and epo-cat:hasHazardousItemUNDGCode is 0..1

Proposed change

Change the cardinalities to 0..n

epo-cat:Item ---- epo-cat:hasHazardousItemUNDGCode -- 0..* --> at-voc-new:dangerous-goods-list
- epo-cat:hasHazardousClass [0..*]
